  • Patent number: 5102051
    Abstract: A spray gun operable by low pressure high volume air is described. The spray gun (10) comprises an air cap (128) formed with a central spraying aperture and a fluid nozzle (70) projecting toward the spraying aperture, the profile of the nozzle is a plain frustum of a core terminating at a small front face bounding an orifice through which fluid is discharged. The arrangement being such that in operation a flow of atomizing air that emerges through a gap between the nozzle (70) and the air cap (128) attaches to the nozzle (70) and to an emergent fluid jet which assumes a conical form that is a continuation of the nozzle surface and changes to a parallel jet before it breaks up into atomized droplets.
